2024 Primera B de Chile

The 2024 Primera B de Chile, also known as Campeonato Ascenso Clínicas ACHS Salud 2024 due to sponsorship by the Chilean Safety Association (ACHS), is the 70th season of the Primera B de Chile, Chile's second-tier football league. The fixture for the season was announced on 24 January 2024, with the competition beginning on 23 February 2024.

Format
The competition is run under the same format used in the most recent seasons, in which the 16 participating teams will play each other in a double round-robin tournament (once at home and once away) for a total of 30 matches, with the top team at the end of the 30 rounds winning the championship as well as promotion to the Campeonato Nacional for the following season. The next seven best-placed teams at the end of the regular season will take part in a play-off tournament to decide the second promoted team (Liguilla), with the league runners-up receiving a bye to the semi-finals. The playoffs winning team will be the second and last promoted team to the top flight for the following season. The bottom-placed team at the end of the regular season will be relegated to the Segunda División Profesional.

Teams
The tournament is played by 16 teams, 13 of them returning from the previous season, two relegated from the 2023 Campeonato Nacional (Magallanes and Curicó Unido), and the 2023 Segunda División Profesional champions Deportes Limache. These teams replaced Cobreloa and Deportes Iquique, who were promoted to the 2024 Campeonato Nacional, as well as Deportes Puerto Montt, relegated to Segunda División for this season.
